new i1pro 2 spectrophotometer - Page 2

sweet !

A few quick notes on the i1Pro 2:

- OEM pricing and availability has not been announced yet just retail prices
- In order to take advantage of the new features within the i1Pro 2 you will need updated software that supports it
- A i1Pro 2 can be used as a i1Pro with older/legacy software but only in legacy mode
- does read a bit faster but only marginal
- does read a bit lower light but only marginal
- requires the calibration base plate for dark calibration offset
- when using it’s calibration base plate for dark offset it will also self calibrate the sensor alignment
- still requires a high current USB port but will warn you if the power on the USB is not sufficient
- has a dynamic dark calibration timer with up to several hours on a single dark offset
- has indicator LEDs on top used for information on processes

From all our testing the most and significant improvement we have seen is the dynamic dark cal timer and greatly improved thermal isolation. In most cases we were able to go several hours before the sensors needed another dark cal. This was true even on high ambient temperature displays like Plasma. So for most the i1Pro 2 will be a single dark cal and forget.

Derek, Retail Version will work with CalMAN 4.6x Software?

Yes i1Pro 2 Retail and OEM

Does i1PRO2's Dual Illuminant Design (using both Tungsten Bulb & UV-LED) gives more accurate readings compared with the original i1PRO?

For illuminant readings yes but how often do you use illuminant readings in HT? Yes CalMAN does support the i1Pro and i1Pro 2 in illuminant mode but that is mostly used in print and textiles. I guess you could use illuminant mode on a FP screen surface to measure it's properties?

One advantage of the new illuminant design is how they now perform the auto sensor shift calibration on the white cal base plate during a dark cal offset. How a spectro works is you split the incoming light into multiple beams usually 40-400 parts. Those beams of light are focused on a array of sensors and where each beam of light hits the sensors element determines it’s nanometer value 380-780Nm. This is the mechanical alignment part of calibrating a spectro. In the lab it is done by a known very narrow band light source. So for instance on the i1Pro let’s say 390-400Nm is hitting sensor elements 4-6 that calibration is done at the factory. Now with its built in illuminants the i1Pro 2 does this in the field and is done each time CalMAN does a dark calibration offset, to ensure you get the most accurate calibration each time you use the i1Pro 2. This is also one of the reasons the i1Pro 2 can go much longer between dark cal’s up to several hours now.

So, would the Pro 2 be better for those people trying to measure screens than the Pro 1? I think the guys over at HTshack have been using the Pro 1 to measure both manufacturer and DIY screens.

It looks like the Pro 2 might be an alternative to my Datacolor Mercury for measuring color on leather. My only issue is I would have to build a database for color matching.

so, the new i1Pro 2 is not as huge of an improvement over the old one like the D3 was over the D2?

Huge improvements yes over the i1Pro but for the industries it is primary designed for: print and photography. Our use of the i1Pro or i1Pro 2 in HT are secondary but we did get better initial accuracy and accuracy over time.

are you referring to the dark reading offset or something else here?

Specs.	i1PRO	i1PRO2
Spectral Analyzer	Holographic diffraction grating with 128-pixel diode array	Same with i1PRO
Spectral Range	380 - 730 nm	Same with i1PRO
Physical Sampling Interval	3.5 nm	Same with i1PRO
Optical Resolution	10 nm	Same with i1PRO
Spectral Reporting	380 ... 730 nm in 10 nm steps	Same with i1PRO
Measurement Scan Frequency	200 measurements per second (Rev. D)	Same with i1PRO
Measurement Range	0.2 - 300 cd/m2 on a typical LCD-Monitor	0.2 - 1200 cd/m2 on a typical LCD-Monitor
Short-term Repeatability	x,y: +/- 0.002 typical (5000°K, 80 cd/m2)	Same with i1PRO
Inter-Instrument Agreement	0.4 ∆E94* average, 1.0 ∆E94* max.	Same with i1PRO
Short-term Repeatability	0.1 ∆E94* on white	Same with i1PRO

1200 cd/m2 capability is unnecessary for HT conditions.

For Emissive Measurement Mode, the specs seems the same.

Using i1PRO1 in non-contact mode the meter is not influenced by the heat and the temperature is stable over the time. Using iBeamer the dark reading is very fast, without moving the meter.

i1PRO1 was not so accurate for measurements lower than 10 cd/m2, how is the minimum luminance measuring level of 1iPRO2 that we can safely trust?

i1PRO2 generally gives closer xy readings from i1PRO1 versus a JETI or Minotla reference spectro?

I hope Tom Huffman (ChromaPure) can give us an in-depth review of that new i1PRO2 (like the sweet review of i1D3) or Derek Smith (CalMAN) can post any comparison Test from SpectraCAL's Labs after NAB.

BTW, X-Rite will announce an upgrade discount offer for i1Pro1 users on the weekend.

That's what we all should be waiting for. Is the new meter worth it for our purposes?



Thanks, Ted. Looking forward to seeing their offer.

bump, could you elaborate?

I hoped for a bigger upgrade, like ~5nm optical resolution (after their „revolutionary” colorimeter I expected a „revolutionary” spectro...).
And possibly an emissive only variant without (or with disabled) lamp(s) and D65 based factory calibration.


There is something I don't really understand.
As much as I know the aging and drifting of the built-in lamp was a bigger problem than the drifting of the sensor accuracy. And now they wish to use that lamp on the white tile not to correct the lamp drift but the sensor drift?
Did they improve the stability and reliability of the lamp this much or...?

They use the LED, the LED they put into it has a very narrow spike at a known wavelength.

Since they know where that spike falls they do the sensor alignment based on that.

Thanks, it makes sense now.


By the way, some of the new features sound like X-Rite actively followed the development of the unofficial ArgyllCMS software. And yet they didnt't send one of these for Greame.

Discounts announced today by X-Rite but they don't offer any saving for i1PRO retail / i1 Basic owners.

I hope the OEM version will have lower price than the retail version, without X-Rite's i1Profiler licence and without the accessories that can be used only with i1Profiler software like:

- the aluminum ruler system for making chart measurements

- spot color positioning target

- water-resistant, canvas carrying case to make transporting and storing your i1 system a snap.

Pricing: may be accurate, maybe not.....

From here.

Set prices are as follows:
I1Basic Pro 2 - 4529 net, 5570 gross 4529 = US $1427
I1Photo Pro 2 - 5849 net, 7194 gross
I1Publish Pro 2 - 7929 net, 9754 gross


Mid-market rates: 2012-04-23 01:05 UTC
1.00 USD = 3.17327 PLN
US Dollar Polish Zloty
1 USD = 3.17327 PLN 1 PLN = 0.315132 USD

Ah, it's out in the US. It won't be long before we see some flat panel/projector specific reports then.

Any news on this front?

Attendees will learn about upgrade options, new software features, and more. There will be an opportunity for questions after the presentation.

To register for this webinar at 12:00 PM EDT, visit: www2.gotomeeting.com/register/690804266

I wonder when these will be available from Spectracal and Chromapure?

Soon from SpectraCal, we just got our OEM pricing, now checking on availability. CalMAN v4.6 already has i1Pro 2 support in we just need the meters now

will the old i1 Pro be sold at a significant discount once the new one is for sale?

Not sure what you mean? The OEM i1Pro Rev D with no longer be avaliable once the OEM i1Pro 2 is shipping.

We will have a trade in program for those with a older i1Pro wishing to get a i1Pro 2. From those traded in we will offer re-certifed used i1Pro for sale while they last.

I am very happy to hear that there will be a trade in program. I am quite anxious to get one of these to replace my i1Pro. Thanks for the update Derek.

What I mean is that you're currently selling it for $1029 on the SpectraCal site. Will the remaining stock be sold at a lower price before the inventory is completely emptied?

EDIT: Will the re-certified used i1Pro's be sold on the SpectraCal site directly?
